Appendix B: Beeps, Lights and Errors
Beep and Light Sequences
LabPro makes use of three LED indicators and four kinds of sounds:
•
A red LED (error indicator).
•
An amber LED (warning indicator).
•
A green LED (ready indicator).
•
A low tone followed by a high tone (low-to-high beep).
•
A medium tone followed by another medium tone (medium-medium beep).
•
A high tone followed by another high tone (high-high beep).
•
A “tick” sound when a key is pressed.
The following bullets explain when beep and light sequences normally occur and what the sequences
mean.
•
When LabPro completes initialization, you will hear the startup sequence: high-high beep,
medium-medium beep, low-to-high beep (6 total beeps, plus LEDs light up in this order: red LED,
yellow LED, and green LED)
•
When you press the QUICK SETUP button:
−
the medium-medium beep sounds if an Auto-ID sensor is attached to LabPro.
−
the high-high beep sounds if no Auto-ID sensors are attached to LabPro.
•
When LabPro is connected to a calculator during sampling commands:
−
the medium-medium beep sounds when initializing data collection.
−
the medium-medium beep sounds when starting data collection (transition from pre-store to
store).
−
the medium-medium beep sounds when completing data collection.
Note 1: If the sampling timing causes the beeps to run together, LabPro software may not sound all the
beeps.
Note 2: You will not get all the beeps when Fast Sampling is enabled.
Note 3: You will not get all the beeps when using triggering.
•
Hold the Start/Stop button for 5 seconds (firmware version 6.022 or newer only) to reset the
LabPro.
•
When you set LabPro for manual trigger and press the START button, a medium-medium beep
sounds.
•
When you press the TRANSFER BUTTON:
−
the low-to-high beep sounds when the transfer succeeds.
−
the high-high beep sounds if the transfer fails for any reason.
•
When an overcurrent condition is detected, five high-high beeps sound. (This causes an error,
which causes even more beeps to sound.)
•
When LabPro begins a full self-test, three low-to-high beeps sound.
•
When self-test completes:
−
the low-to-high beep sounds if self-test passes.
−
the high-high beep sounds if self-test fails.
•
When LabPro’s base code detects an error in the commands sent from the host, a high-high beep
sounds twice (4 high pitch beeps in a row.)
•
When LabPro powers up:
−
two high-high beeps sound if the base code is not loaded.
−
three high-high beeps sound if the power-up self-test fails.
